In which of the following method teacher and student interchange their roles ?

The correct answer is Reciprocal teaching.

Reciprocal teaching is an instructional activity that takes place in the form of a dialogue between teachers and students regarding segments of text. In this method, the teacher and students switch roles to lead the discussion using four specific strategies: predicting, clarifying, questioning, and summarizing.

Let's look at why the other options are not correct:

• Conditioned learning: Refers to a learning process where a behavior becomes associated with a specific stimulus (e.g., classical or operant conditioning), involving no exchange of teaching roles.

• Receptive learning: Describes a passive mode of learning where the student simply receives and absorbs information presented by an instructor or textbook.

• Expository teaching: Is a traditional, teacher-centered approach where the educator directly presents structured information and explanations to passive learners.
